How does TB cause pneumothorax?
Pneumothorax secondary to TB usually occurs after extensive TB involvement of the lung, and the sudden onset of bronchopleural fistulization and empyema12 with severe cavitary formations or occasionally with miliary TB. The TB organism invades the pleura and causes liquifactive necrosis, then pleural rupture.
What is pneumonia tuberculosis?
Acute tuberculous pneumonia (TP) is similar to typical bacterial pneumonia, and it is one of the causes of childhood illness [2]. Acute TP generally refers to the clinical manifestations of community-acquired pneumonia (CAP), but the pathogen is M. tuberculosis instead of non-tuberculous bacteria or viruses [3].
What is the difference between pulmonary TB and miliary TB?
Tuberculosis (TB) is a serious infection that usually affects only your lungs, which is why it’s often called pulmonary tuberculosis. However, sometimes the bacteria get into your blood, spread throughout your body, and grow in one or several organs. This is called miliary TB, a disseminated form of tuberculosis.
How rare is miliary TB?
It is estimated that miliary TB accounts for about less than 2% of all cases of TB in immunocompetent persons and up to 20% of all EPTB cases. Of 11,182 incident cases reported in the United States in 2010, EPTB accounted for approximately 22% of cases; miliary disease was reported in 299 (2.7%).
What are the complications of tuberculosis?
Tuberculosis complications include:
- Spinal pain. Back pain and stiffness are common complications of tuberculosis.
- Joint damage.
- Swelling of the membranes that cover your brain (meningitis).
- Liver or kidney problems.
- Heart disorders.
Is spontaneous pneumothorax a lung disease?
A spontaneous pneumothorax is the sudden onset of a collapsed lung without any apparent cause, such as a traumatic injury to the chest or a known lung disease. A collapsed lung is caused by the collection of air in the space around the lungs.
Can miliary TB be cured?
If left untreated, miliary tuberculosis is almost always fatal. Although most cases of miliary tuberculosis are treatable, the mortality rate among children with miliary tuberculosis remains 15 to 20% and for adults 25 to 30%.
Why does miliary tuberculosis occur?
Causes of miliary TB TB is caused by bacteria called Mycobacterium tuberculosis. It’s contagious and is transmitted when someone with an active TB infection in their lung releases the bacteria into the air by coughing or sneezing, and someone else inhales it. It can stay airborne for a few hours.
